DETAILED DESCRIPTION
The technical solutions in the embodiments of the present
application will be described clearly and completely hereinafter in
conjunction with the drawings in the embodiments of the present
application. Apparently, the described embodiments are only a part
of the embodiments of the present application, rather than all
embodiments. Based on the embodiments in the present application,
all of other embodiments, made by the person skilled in the art
without any creative efforts, fall into the scope of the present
application.
A simulation system for a current collecting surface of a C-shaped
contact rail is provided according to the present application,
which avoids the problems of long production cycle, high cost and
inapplicability to a test line of a C-shaped contact rail resulted
from using the C-shaped contact rail.
For those skilled in the art to better understand solutions of the
present application, the present application is described in detail
hereinafter in conjunction with drawings and embodiments.
Referring to FIG. 1, a simulation system of a current collecting
surface of a C-shaped contact rail according to an embodiment of
the present application includes an H-shaped rail 10 and a limiting
plate 20.
In a solution according to the present application, referring to
FIG. 2, a lower surface of the H-shaped rail 10 is formed by a
first plane 101 and a second plane 102 intersecting with each
other. An included angle formed between the intersecting first
plane 101 and second plane 102 is a first preset angle. Here, the
first plane 101 is parallel to the horizontal plane, and the first
plane 101 has a fixed length.
In this solution, referring to FIG. 3, the limiting plate 20
consists of three supports, including a first support 201, a second
support 202, and a third support 203 which is perpendicular to the
horizontal plane.
The respective structure of the three supports of the limiting
plate 20 and the connecting relationship therebetween are as
follows. The first support 201 has a first end fixed to the third
support 203, and has a second end suspended, and the first support
201 keeps level. The second support 202 has a first end fixed to
the third support 203, and the second support 202 is arranged at a
specified angle, i.e., a second preset angle, with respect to the
horizontal plane, and the second preset angle may be 5 degrees.
A distance between the first support 201 and the second support 202
is a specified value, which is greater than the height of the
H-shaped rail 10.
The H-shaped rail 10 and the limiting plate 20 are connected to
each other in such a manner that an upper surface of the H-shaped
rail 10 is fixedly connected to a lower surface of the first
support 201 of the limiting plate 20.
The simulation system for the current collecting surface of the
C-shaped contact rail according to this embodiment consists of the
H-shaped rail 10 and the limiting plate 20 which can simulate a
C-shaped contact rail. In the present application, the current
collecting end surface of the H-shaped rail 10 has the same current
collecting area as an actual C-shaped contact rail. Furthermore,
after the limiting plate 20 and the H-shaped rail 10 are assembled
and connected, the outline of the assembly of the limiting plate 20
and the H-shaped rail 10 matches with an outline of an inner
contour of a C-shaped contact rail.
On this basis, the simulation system according to the present
application mounted on a test line can well simulate the current
collecting situation of a train under the condition of a C-shaped
contact rail. The simulation system for the current collecting
surface of the C-shaped contact rail according to the present
application uses the combination of the limiting plate 20 and a
conventional H-shaped rail 10, and has a short production cycle, a
low cost, and an applicability to the test line compared with the
solution of re-producing a C-shaped contact rail which has been
discontinued.
In a specific embodiment, the first preset angle between the first
plane 101 and the second plane 102 is 176 degrees, i.e., an
included angle between the second plane 102 and the horizontal
plane is 4 degrees.
With such an angle, it is not required to reduce the thickness of
the second plane 102 of the lower surface of the H-shaped rail 10
by a large margin, thereby not only ensuring the strength of the
H-shaped rail 10 itself, but also allowing an effective current
collecting area of the H-shaped rail 10 to be same as an effective
current collecting area of a C-shaped contact rail.
Based on the above embodiments, the first plane 101 has a length of
47 mm, in this way, the length of the first plane 101 matches with
the length of a current collecting end surface of the C-shaped
contact rail, thereby realizing an accurate simulation of the
current collecting end surface of the C-shaped contact rail. Test
data obtained during testing the current collecting situation of
the train in the test line are more accurate.
Apparently, in a specific embodiment, the H-shaped rail 10 is
embodied as a relatively common steel-aluminum composite H-shaped
rail, which further saves the cost and shorten the production
cycle.
Based on the above embodiments, each of the first plane 101 and the
second plane 102 of the lower surface of the H-shaped rail 10
according to an embodiment of the present application is a steel
plane, has a large rigidity, and is not easy to be deformed, and is
not easy to be damaged by an external force, thus the service life
of the H-shaped rail is prolonged.
In another embodiment according to the present application, the
distance between the first support 201 and the second support 202
of the limiting plate 20 is a specified value, which conforms to a
geometrical dimension of an inner contour of the C-shaped contact
rail. In this way, it is better to test whether a phenomenon of
exceeding the boundary or scraping the collector shoe occurs during
the operation of the train. In the case that the H-shaped rail 10
is a standard H-shaped rail, since the distance between the lower
surface of the H-shaped rail 10 and the second support 202 is 86
mm, the distance between the first support 201 and the second
support 202 is 190 mm.
Apparently, the distance between the first support 201 and the
second support 202 may also be set as other values according to
various types of H-shaped rails.
It is to be noted that, the distance between the first support 201
and the second support 202 may be understood as the distance
between the lower surface of the first support 201 and an upper
surface of the second support 202, and may also be understood as
the distance between a central point of the first support 201 and a
central point of the second support 202.
Further, since the second support 202 is not a horizontal line, the
distance between the lower surface of the first support 201 and the
upper surface of the second support 202 may be referred to as the
distance between a lower surface of the second end of the first
support 201 and an upper surface of the second end of the second
support 202.
In other embodiments according to the present application, the
second end of the first support 201 of the limiting plate 20
further has a bent portion bending downwards, which achieves a good
insulation effect.
Based on the above embodiments, the limiting plate 20 may be made
of glass fiber reinforced plastic. The glass fiber reinforced
plastic has a good rigidity, and is a good insulation material, and
thus is adopted as the material of the limiting plate 20, which
well insulates the current collecting portion of the train from the
environment. Thus the safety is better.
In another embodiment according to the present application,
referring to FIG. 4, the limiting plate 20 further includes a
fourth support 204. The extending direction from a first end to a
second end of the fourth support 204 is opposite to the extending
direction from the first end to the second end of the first support
201. In this way, the fourth support 204 may fix the whole
simulation system. To fix the simulation system, it is simply
required to fix the fourth support 204 to the test line.
Furthermore, the fourth support 204 may further function as a
reinforcing rib, which prevents the simulated C-shaped contact rail
from being deformed.
On the basis of the above embodiments, the included angle between
the second support 202 and the horizontal plane, i.e., the second
preset angle, is a specified value, which conforms to a geometrical
configuration of an inner contour of the C-shaped contact rail.
A simulation system for a current collecting surface of a C-shaped
contact rail according to the present application is described in
detail hereinbefore. The principle and the embodiments of the
present application are illustrated herein by specific examples.
The above description of examples is only intended to help the
understanding of the principle and the spirit of the present
application. It should be noted that, for the person skilled in the
art, a few of modifications and improvements may be made to the
present application without departing from the principle of the
present application, and these modifications and improvements are
also deemed to fall into the scope of the present application
defined by the claims.
